From fcbcc576a22295afa3e6188657387c630575dade Mon Sep 17 00:00:00 2001 From: MechaCat02 Date: Thu, 4 Jun 2026 20:18:50 +0200 Subject: [PATCH] feat(v1.1.6): realtime channels + v1.1.5 follow-ups + version bumps Server-side realtime SSE on per-app pub/sub topics, plus the three v1.1.5 follow-ups and the version bumps. Realtime: - topics registry (0021) + admin endpoints + Capability::AppTopicManage (-> app:admin; no new scope). - GET /realtime/topics/{topic} SSE endpoint (orchestrator-core data plane): Host -> app, RealtimeAuthority gate (404 missing/internal, 401 bad/absent token), broadcast::Receiver stream + heartbeat. - RealtimeBroadcaster / RealtimeEvent / RealtimeAuthority traits (picloud-shared); InProcessBroadcaster + GC (orchestrator-core); DB-backed RealtimeAuthorityImpl (manager-core). Publish path fans out to in-process subscribers after the durable outbox commit (best-effort, panic-isolated). - HMAC subscriber tokens (subscriber_token.rs) + app_secrets table (0022) + pubsub::subscriber_token SDK (schema 1.6 -> 1.7). TTL clamp + env overrides. - Dashboard Topics tab (register/list/edit/delete, prominent external badge, flip confirmation). v1.1.5 follow-ups: - Empty blobs accepted (NewFile/FileUpdate::validate) + round-trip test. - Orphan *.tmp.* sweeper (spawn_files_orphan_sweep). - Dispatcher e2e tests, one per trigger kind (DATABASE_URL-gated). Versions: workspace 1.1.6, SDK 1.7, dashboard 0.12.0. Schema-snapshot golden re-blessed.
